Largest, Most Comprehensive Forecast Study Confirms AccuWeather's Superior Accuracy with #1 Ranking

Independent study verifies AccuWeather lead position in analysis of 30 million temperature, wind, and precipitation forecasts in the U.S. and around the world.

AccuWeather Global Weather Center -- September 5, 2017 -- In the most comprehensive study ever undertaken of forecast accuracy, AccuWeather was overwhelmingly confirmed as the most accurate source of weather forecasts and warnings in the U.S. and everywhere in the world. The independent analysis of 30 million weather forecasts by industry tracker ForecastWatch concluded that AccuWeather had the highest level of forecast accuracy in forecasts of temperature, precipitation and wind.

Severe weather kills approximately a half a million people globally each year and leaves tens of millions of people injured. The nation's fourth largest city and many nearby communities just experienced what AccuWeather was the first to call the costliest weather disaster in U.S. history with Hurricane Harvey, estimating the toll on the GDP in excess of $190 billion. Having the most accurate forecasts and warnings available and further ahead than any other source is critical for evacuation planning and survival in the event of a natural weather disaster. To stay on top of the latest news and information regarding severe weather updates this hurricane season or to donate to numerous non-profit organizations providing critical aid to hurricane victims, visit or download the AccuWeather app.

Inclement weather interrupts business operations and causes a myriad of disruptions for people and businesses, including cancelled plans, interrupted travel, and costly shut downs. According to National Oceanic and Atmospheric Association or NOAA, the U.S. has already experienced 10 natural weather disasters costing more than $1 billion in 2017 alone. The more accurate weather forecasts and warnings are, the more lives saved, and the more people and businesses can plan around the impacts of harsh weather on their lives and businesses.

"We are in the business of keeping people safe. These results are extremely gratifying to our creative, innovative and talented team who work diligently every day to provide the most accurate, impactful and useful forecasts to people in the United States and around the world," said Dr. Joel N. Myers, Founder, President and Chairman of AccuWeather. "This report reinforces the amazing work we do to keep people out of harm's way. This has been especially apparent this hurricane season, and we will continue to focus on providing and communicating the most accurate forecasts and warnings as well as their relevant impacts on lives and businesses as we always have."

This extremely detailed and thorough analysis of verification of weather forecasts confirms what other studies and statistics have shown -- that AccuWeather forecasts and warnings are the most accurate available to all. The verification statistics were focused on forecast factors of most value to users. Data for the analyses was gathered from 1,145 locations in the U.S. and other parts of the world over a 12-month period in calendar year 2016. More than 30 million one-day to five-day forecasts were obtained and analyzed from six weather providers, comparing temperature, precipitation and wind-speed forecasts, proving that AccuWeather is the clear leader.

Vice President of Innovation and Development Jonathan Porter says the findings detailed in this independent report are proof of AccuWeather's accuracy and ongoing commitment to advancing the science and business of meteorology, which are yielding substantial benefits to people and businesses.

"Accuracy plus weather is our name," said Porter. "Our company is solely focused on Superior Accuracy and has been employing AI and data science for decades to protect lives and property, reduce risk and help people and businesses get more out of each day. Having the most accurate forecasts and warnings means more lives saved, reduced bodily harm and prevention of property losses. For business, it means reduced risk and liability. It's rewarding to have an independent source back up our claims."

According to Myers, AccuWeather's success is attributable to what he describes as the "human-machine mix," utilizing and integrating the very best scientific tools, most complete and accurate data and models and the most talented team of forecast meteorologists on the planet. By combining the best forecast models available, the greatest amount of big data integrated with leading-edge predictive AI, the most advanced weather forecast engine, with the most talented and experienced operational forecast meteorologists working with research and development experts, AccuWeather has developed a unique approach to providing valued weather forecasts.

And the company says having the most accurate weather forecasts is only part of its proven track record with many of its long-term clients, including 245 of the Fortune 500 companies and thousands of other businesses and government agencies globally.

Said Myers, "Key to people and businesses getting the most value from AccuWeather forecasts and warnings also comes from effectively communicating of the impact of weather events on peoples' lives -- and that all begins with forecast accuracy."
